Answer:
Black clover is a good one :)
Step-by-step explanation:
If you want to know how ABC turned to A'B'C', then
(assumption)
It may be shape ABC was rotated 180 degrees counterclockwise/clockwise, since the rules for rotating a shape 180 degrees is (x,y) -> (-x,-y)
i may be wrong
(8*5*4) + (4*4*4)
8*5*4 for the prism at bottom
4*4*4 for the cube on the top
When values of a quadratic function are listed in a table with x-values having a constant difference, the y-vlaues will have a constant (non-zero) second-difference.
Here, we can list first and second differences for the values in the given tables to identify the quadratic function.
Table 1.
- 1st differences: 3, 3, 3, 3
- 2nd differences: 0, 0, 0, 0 . . . . this is a linear function
Table 2.
- 1st differences: -6, -2, 2, 6
- 2nd differences: 4, 4, 4 . . . . this is a quadratic function
Table 3.
- 1st differences: 5, -8, -3, -3
- 2nd differences: -13, 5, 0 . . . . can be described by a 4th degree polynomial
Table 4.
- 1st differences: 3, 0, -3, -3
- 2nd differences: -3, -3, 0 . . . . can be described by a 4th degree polynomial
___
The appropriate choice is Table 2.
Answer:
3x + 3y - 3 units each
Step-by-step explanation:
An isosceles triangle is one that has two equal sides and angles.
given: perimeter = 7x + 5y - 8 units
base length = x - y -2 units
The length of each congruent sides can be determined as follows:
Let the length of the sides be represented by t. Since the sides have equal length, then;
7x + 5y - 8 = t + t + (x - y -2)
7x + 5y - 8 = 2t + (x - y -2)
⇒ 2t = 7x + 5y - 8 - (x - y -2)
= 7x + 5y - 8 - x + y + 2
collecting like terms,
2t = 6x + 6y - 6
= 2(3x + 3y - 3)
divide both sides by 2,
t = 3x + 3y - 3
Therefore, the congruent sides are 3x + 3y - 3 units each.
